Scientific paper

The 1980-1981 photoelectric observations by Srivastava and coworkers of the eclipsing binary BZ Eridani in U, B, and V filters (using the 38-cm reflector of the Uttar Predesh State Observatory) are presented, including the first period study of the system. The new period was determined to be 0.6641703 d. The features of BZ Eri were found to be changing. The large scatter around the phase of the secondary minimum, the light distortions throughout the cycle, and the finding by Srivastava and Uddin (1985) that the O-C values of the secondary minimum show stronger fluctuations than the primary minimum, indicate that both components of BZ Eri are responsible for changing its features.
